Patent GB-2094583-A (GB)
Title: Binary signal processing circuit
IPC: H04H20/88
Filed: 1982-03-08
Abstract: The circuit in accordance with the invention has for its object to determine whether a binary signal is subjected to fluctuations or not. A product circuit (16) is provided two inputs of which receive the binary signal and the inversion of the binary signal, one being applied directly and the other via a first low-pass filter (15). The product circuit (16) is of such a structure that its output signal is equal to zero only then when the two input signals each correspond to one of the two states of the binary signal. If the binary signal fluctuates then the output signal of the first low-pass filter (15) assumes a value which is located between the two binary levels, and consequently in this case the output signal in the product circuit (16) differs, at least temporarily, from zero. Via a second low-pass filter (19) the output signal of the product circuit is applied to a threshold value circuit (20) the switching state of which indicates whether the signal to be processed fluctuates (often) or not. <IMAGE>

Title: Card readers
IPC: G07D7/04
Filed: 1982-04-08
Abstract: A security document includes a security thread which carries a code, constituted by magnetisable and non- magnetisable portions. The code is a multiple bit code. The position of the thread and its orientation relative to a reading machine can vary within wide limits. The code is read by passing the document under a head which applies a magnetic field to the thread and thereafter the thread is passed under an array 11 of magnetic reading heads which are scanned to provide a repetitive time varying signal representing the code on that part of the thread which has been read. The bits may be read in parallel or sequentially. An array of amplifiers 13 temporarily store the peak voltages derived by the reading heads. A multiplexer 14 sequentially scans the stored signals to derive a time varying signal representative of the binary code. <IMAGE>

Patent GB-2135414-A (GB)
Title: Emergency braking of railway vehicles
Inventor: HART JAMES EDWARD
IPC: B60T15/36
Filed: 1984-02-23
Abstract: In the braking apparatus as disclosed in Patent Application No. 2085106A, an inshot valve device 31 controls the brake-actuating decreasing pressure so that there is a constant braking force for a certain period after an initial rapid run-in of slack between vehicles and before a further rapid build-up of braking forces. Normally the pressure is applied to both sides (chambers 106, 108) of piston 105, which due to spring 155 acts on rod 109 to open valve 110, 111 allowing the pressure to vent. Under emergency operation, this pressure is trapped at a particular value in chamber 108 and timing chamber 151 connected thereto, while open valve 110, 111 allows the decreasing pressure to act in chamber 106. Thus, piston 105 rises against spring 155 and valve 110, 111 closes holding the braking pressure constant. Valve 107 simultaneously opens so that trapped pressure in 151, 108 acts over a greater area of piston 105 but also escapes for the certain period of time via choke 190, whereafter piston 109 falls and re-opens valve 110, 111. <IMAGE>

Title: A system for delivering a quantity of fluid
Inventor: GILL DAVID CHARLES
IPC: A01M7/00
Filed: 1984-03-20
Abstract: Fluid such as herbicide is applied from heads (112, 114) including rotary distribution members. Fluid is supplied to the heads (121, 114) from a pump (102). The pump is driven by a permanent magnet d.c. motor, the speed of which depends on its operating voltage. The speed of the motor is monitored by monitoring variations, e.g. due to commutation, in its supply current, compared with a reference signal, and adjusted by adjusting its operating voltage to maintain a correct speed. The reference signal may be a function of the travel speed of the equipment, so that the delivery rate of the fluid varies with the travel speed. <IMAGE>

Title: Determining the location of defects present in flat glass
Inventor: RENARD GUY
IPC: G01N21/896
Filed: 1985-04-02
Abstract: The locations of defects in flat glass (1) are detected during conveyance through a detection station where the glass is scanned by a radiation beam (11). The beam sweeps transversely across the path of the glass through a distance in excess of the glass width so that the beam sweeps through both side edges. Beam deflection occurs when the beam encounters a side edge boundary of the glass (1) and beam deflection or attenuation occurs when the beam encounters a defect. Photodetectors (22,23) are located so that their irradiation or non- irradiation by the beam after it has passed through the glass depends on beam defections or attenuations by the glass, in particular detector 23 receives the beam when undeflected and detector 22 when deflected. Pulses of light are received by a detector 15 from a striped mirror 13 to indicate the position of the beam. The photodetectors are connected to a signal processor from which output signals are obtained indicative of the locations of the defects in the lengthwise direction of the glass and indicative of the transverse distances between such defects and a side edge of the glass. <IMAGE>
